A wedding for ex-Warrior and current Maverick Harrison Barnes became a LeBron James mock-session when one of James’ jam-out songs was played, with Stephen Curry imitating a dance the Cavaliers superstar posted on Instagram last month.

More relevant, though: That other Cavaliers superstar — the one who wants out — couldn’t stop laughing at his supposed arch-nemesis teasing his supposed teammate.

And the Kyrie Irving saga adds a petty, high school flare to it.

Saturday, during Barnes’ reception, Tee Grizzley’s “First Day Out” came on, the same song James used to pump himself up during an Instagram video on June 15. Curry has seen it, apparently enough to do his own version of James’ intense dance, poking fun at the NBA’s best player in the comfort of privacy and friends.

Except others — and James — now can see behind the curtain because an Instagram user uploaded the clip (and then deleted it, but not before others had captured it). And what stands out is that in the crowd, which Curry is amusing with a joke at James’ expense, is Irving, egging on his supposed enemy.

The video adds another exceedingly trivial twist to the Cavaliers’ hectic offseason, in which they are now trying to ship Irving away and trying to gear up for another NBA Finals run. All eyes though, for now, are on James’ Instagram account for a response.
